Opening Workspace redirects to spinning cloud9 page


#1

I’m new to cloud9 as a student. I created my free cloud9 workspace just yesterday Dec 12, 2018. Today Dec 13, when I click on mysql_course Open workspace, it redirects to a cloud 9 page and the spinning does not stop.
My cloud9 workspace link: https://c9.io/c92018

Here is the redirected page and screenshot:

Thank you for your help.
